MINERS TOOL.

SPECIFICATION forming part of LettersPatentNo. 753,048, dated February 23, 1904.

Original application filed July 19, 1902, Serial No. 116,269. Divided and this application iiled May 15, 1903. Serial 110.157,245. (No model.)

To 'all whom it may concern:

Be it known that I, ALFRED VICTOR Das MOINEAUX, a citizen of the United States, and a resident of Silverplume, in the county of Clear Creek and State of Colorado, have invented a new and useful Improvement in Miners Tobls, of which the following is a full, clear, and exact description.

This invention relates to a tool for use by Io miners in preparing a blasting-fuse for service; and the subject-matter of this application is in part a division of a prior application filed by me on July 19, 1902, Serial No. 116,269.

The object that 1 have in view is to provide the tool with means for splitting the end of a fuse and with a guide by which the fuse may be presented properly to the slitting devices and also held rmly in place during the slitting operation. I zo Further objects and advantages of the invention will appear in the course of the subjoiued description, and the novelty will be dcned by the annexed claims.

Reference is to be had to the accompanying 2 5 drawings, forming a part of this specification,

in which similar characters of reference indicated corresponding parts in all the figures.

Figure 1 is a perspective View of a miners tool constructed in accordance with my invention. Fig. 2 is a plan view'of the tool with one of the handle-plates removed to show the form of the powder-lance. Fig. 3 is an edge view of the tool illustrated by Fig. 2. Fig. f1 is an inverted plan v iew of the tool in its closed position. Fig. is a cross-section on the line 5 5 of Fig. 2. Fig. 6 is an end elevaprovided with handles 10 11, respectively, and said members are formed on the opposite side of the pivot from their handles with the jaws 12 13. The jaws 12 13 are provided with the recesses 15 15, respectively, and these re- 5C cesses are beveled in opposite directions, so as to produce cutting edges adapted to shear past cach other. (See Figs. 2 and 5.) The recesses 15 15 in the companion jaws constitute the means for crimping or compressing a rnetallie cap around a fuse. The jaws are furthermore provided with cutting-recesses 1L 14:, the same being located at points intermediate of the length of the jaws and beyond the crimping-recesses thereof. The recesses 14 111 are beveled to produce cutting edges, which are also adapted to shear past each other, and these cutting-recesses form the means by which a fuse may be severed. The cuttingrecesses `1li 14; of the jaws have long beveled 65 surfaces which produce sharp-cutting edges; but the crimping recesses have somewhat shorter beveled surfaces which do not, however, produce eutting edges, thus forming blunt edges in the crimping-recesses as compared with the sharp edges of the cutting-recesses.V A"

To increase the capability of service'of the implement, I provide the jaws with means whichserve to slit the end of a fuse, and in attaining this object I prolong the ends of the jaws 12 13 beynd the cutting-recesses l5 15a. These prolonged ends of the jaws are beveled on their opposing faces to produce the coperating blades 16 17, the cutting edges of 80 which are indicated at 18. The slitting-blade 17 on one member or jaw of the instrument is somewhat wider than the slitting-blade 16 on the other jaw member, and the beveled edges 18 of these blades are adapted t'o shear 85 past each other, as shown by Fig. 6.

Another feature of the present invention resides in a guide which is fitted to one of itself, thereby forming s cap the length oi' which exceeds the width of the slit'ting-blede to which the guide is applied. The guide oonsists of side members or plates 20 2li which are parallel to each other, and one of the plates is bent inwardly, so as to form a recess 22, 'the width of said recess being less than the space between the parallel members il() 2l whereby the cap may have its contracted IO closed portion 22 fitted snugly to the narrow slitting-blade 16. Said guide is adapted to be fastened removably to the blade 16 by suite le l means, such as a pin or screw 23, and the open end of the guide projects a considerable I5 distance beyond the active edge of the slitting-blade 16, to which said guide is fastened.

ln the service of the implement it be opened to readily introduce e cap into the re eessesl and by manipulating the imple 2O ment in a Way to close the jaws seid oep may be crimped or compressed around e, fuse. The fuse may be ont by itting it in the cntting-recesses le 14"' and manipulating the imn plement so as to close the jaws. If it is desired to split one end of a fuse, the jaws should be opened and en end portion of the fuse thrust into the space between the rnern bers 2O F21 ot' the cap, after which the handles may be pressed together and the jaws thereby closed, so that the blades 16 17 will operate eiiiciently on said fuse, t will be observed that they guide directs the slitting; blades properly on the fuse placed therein, and this lguide also serves as a convenient means for holding tlie fuse adjacent to one blade and in the path of the other blade.

The handle 10 of the implement is hollow and provided with a faceplate 241:, adapted to be secured removably in position. Within this hollow handle is coniined a slidable lance blade 25, having a slot 26, which feceivess guide-post 2"?. rlhis lanceblade is provided with a laterally-extending finger 28, that is adapted to iit in either of the notches or sockets 29 30, 'which are provided in the compan- 45 ion handle 6 of the implement. Having thus described my invention, claim as new and desire to secure by Letters Patenti. A rniners tool1 having handles provided with slitting-blades adapted to shear past one another, and e guide-esp "Married by one blade end having open side presented to the the other blade, said cap presenting opposing l spaced members betweeny which. a. fuse may be inserted and into which one of the blades is adapted to be received. t'

2. A miners tool having handles provided" with wide and narrow slitting-blades adapted to sheer past one another, land a guide-csp carried by the narrow blade and presenting en open side toward the Wide blade.

v 3. A rniner"s tool having handles provided with wide and narrow slitting-blades adapted to shear past one another, and a guide -oap having a contracted closed side which envelops the narrow blade and is attached rrnly i' thereto, seid cap being open at its ends and on the Wide side for the insertion of a fuse and. for the free play of the Wide slitting-blade therein,

e. A miners tool comprising pivoted mern- 7 bers having jaws which are provided with terminal slitting-blades7 and e cap provided with e contracted closed portion which is fitted snugly to one of said slittingeble-des and is arranged to project beyond thefeetive' edge '.75 thereof in a positionto reeeivethe companion. slittingblade of the other member.

fin testimony whereof l have signed my name to this specication in the presence of two subseribing witnesses.
